METROL Tool Setter Series for CNC Machining Centers

รายละเอียดสินค้า

Tool Setter Series for CNC Machining Centers

Tool setters are ON/OFF high-precision touch sensors used for positioning cutting tools and nozzles.
Tool condition (length and chips) is monitored to prevent machining defects due to wear and thermal displacement.
※METROL tool setters are best-selling products with over 500,000 units shipped globally in 74 countries.

Why METROL Wins Customers

Reason 01:

Guaranteed repeatability of 1μm, no false positives

Due to coolant splashing and mist inside the machine tool, non-contact sensors may malfunction in some cases.
The tool setter detects the position of the tool by directly touching its leading edge with the contact-surface, thus ensuring consistent, highly accurate detection with a repeatability of 1 micron.

Reason 02:

Fully customizable to match the equipment to be installed

METROL offers a depth of customization options to optimize the tool setter for your operating conditions.
Various contact-surface sizes, measurement direction modifications according to approach direction, detachable contact-surface for cost reduction, lapped finishes and contact shapes are some of the many available options.
This is the unique service offered by a company who has continuously developed and evolved tool setters.

Reason 03:

Overtravel (OT) alarm signal can be activated.

METROL tool setters are equipped with an overtravel signal.
This avoids the risk of damaging the sensor or the equipment spindle in the unlikely event that the tool is pushed too far into the sensor.

Reason 04:

Tool setting for high-speed and small-diameter tools

Built-in bearings designed for high precision enable high-speed tool length measurement. This reduces measurement time, allowing measurement without breaking even the finest 0.2 mm dia. tools.

Reason 05:

Durable protection rating IP67 specification

Excellent durability, having passed rigorous coolant immersion tests and durability tests on actual machining center equipment. It is designed for highly accurate detection even in environments where chips and coolant are scattered.

Benefits

Prevention of machining defects

Because the tool length varies due to thermal displacement and friction, it is necessary to measure the tool before machining starts to determine the machining origin.

Significant reduction of man-hours

Conventional tool setting (external setup)

• Risk of processing defects due to human error
• Time-consuming and labor-intensive tool length measurement adds on non-production time.
• Operators need to set up every time, which makes the site time-constrained.
• Measurement methods become personalized, resulting in handover work and training costs.

Metrol Tool Setter
(on-machine measurement)

• • Eliminates human error when measuring tool length
  • Eliminates 95% of measurement time required to start machining
  • Automated operations allow a fewer number of workers to work on the shop floor and on machine tools.
